Hi, could you send a link to your webpage so we can inspect the issue by ourselves?
For the “We design..” it is a regular page-section in a single-page site. You can download the layout of the complete demo site by importing the theme’s sample data and modify it to your taste afterwards!
I am seeing the logo in all of my browsers both in mac and pc. But I see that you have not set the width and height of the retina logo in theme options. That will make the logo appear in iPhone and iPad. Thanks!
